We're dividing 58969751 by 646 
Our goal is to divide 58969751 by 646.

Step 1:
5 divided by 646 is 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Take the next digit (8) from the dividend and append it to 5, then repeat: 58 / 646

Let's proceed to step 2:
When dividing 58 by 646, we get 0 with a remainder of 58.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 58 and we're left with 58.
Append the next digit (9) from the dividend to 58 and continue with: 589 / 646

Going ahead to step 3:
The number 646 fits into 589 0 times, leaving a remainder of 589.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 589, we get 589.
Grab the next digit (6) from the dividend, add it to 589, then carry on: 5896 / 646

Moving on to step 4:
If we divide 5896 by 646, we get 9 and a remainder of 82.
The next digit of our result is 9. 
Result so far: 9.0
The remainder is 82 after subtracting 5814 from 5896.
Bring next digit (9) of the dividend behind the 82 and repeat the process: 829 / 646

Advancing to step 5:
646 can be fit into 829 1 times, resulting in a remainder of 183.
The next digit of our result is 1. 
Result so far: 91.0
The remainder is 183 after subtracting 646 from 829.
Grab the next digit (7) from the dividend, add it to 183, then carry on: 1837 / 646

Advancing to step 6:
The number 646 fits into 1837 2 times, leaving a remainder of 545.
Use 2 as the next digit of our solution. 
Result so far: 912.0
If we take 1292 away from 1837, we end up with 545.
Bring next digit (5) of the dividend behind the 545 and repeat the process: 5455 / 646

Going ahead to step 7:
646 goes into 5455 8 times with a remainder of 287.
Record the quotient 8 as the next digit in the result. 
Result so far: 9128.0
The remainder is 287 after subtracting 5168 from 5455.
Take the next digit (1) from the dividend and append it to 287, then repeat: 2871 / 646

Advancing to step 8:
646 goes into 2871 4 times with a remainder of 287.
Write down 4 as next digit of the result. 
Result so far: 91284.0
Subtract 2584 from 2871 to get 287.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2870, and continue the process.

On to step 9:
646 goes into 2870 4 times with a remainder of 286.
The number 4 becomes the next digit in our result. 
Result so far: 91284.4
If we take 2584 away from 2870, we end up with 286.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2860, and continue the process.

On to step 10:
646 goes into 2860 4 times with a remainder of 276.
Use 4 as the next digit of our solution. 
Result so far: 91284.44
If we subtract 2584 from 2860, we get 276.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

After the division, we end up with 91284.44 and a remainder of 0.276.
